BMW refers to the X6 Concept, which debuted at the 2007 Frankfurt Motor Show, as a Sports Activity Coupe, a derivation of the Sports Activity Vehicle (SAV) segment it introduced with the X5 back in 1999.
A new drivetrain and chassis control system dubbed "dynamic performance control" makes its world debut in the X6 Concept. As soon as the system detects possible over-or under-steer—on a bend, say—it will combine with the xDrive all-wheel drive to adjust the distribution of drive forces between the two rear wheels for improved stability, traction, and forward motion.
The rakish, 4-door X6 clearly favors form over function. Interior dimensions have not been released, but it is safe to say that some level of backseat headroom has been sacrificed in order to achieve the dramatically sloping roofline. The X6 profile is at its highest point right behind the steering wheel.
The wheel arches are powerful and almost squared off in appearance, while the side character lines mix convex and concave surfaces. The rear end, perhaps the X6's most attractive vantage point, is split and characterized by horizontal lines, making for a wide and powerful stance. Meanwhile, the trademark BMW “Hoffmeister Kink” can be seen at the car’s rear, where the back windows meet the car body.
The Verdict: However unique and attractive this concept may be, BMW is not the first automaker to place a low roofline on a crossover vehicle (just look at the Infiniti FX35/45.) But word on the street is that X6 is a sure bet for production.
